If your network adapter isn’t working properly, there are some steps you can take to troubleshoot and hopefully get it functioning again. Here is a checklist of steps to take:
1. Check the cables: Make sure all the cables connected to your network adapter are firmly in place and undamaged. If any are loose or look like they might be damaged, try replacing them with new ones.
2. Check the drivers: Open your device manager and check that the drivers for your network adapter are up-to-date and functioning properly. If not, try reinstalling or updating the drivers from the manufacturer website or Windows Update.
3. Check the settings: Go into the Network Connections menu and make sure that the settings for your network connection are correct for your setup. This includes the IP address, DNS server, gateway, and other key settings.
4. Reset the router and network adapter: Unplug the router and network adapter from power (or turn off their power switches if applicable) and leave them off for a minute or two. Then plug them back in and wait for them to boot back up. This can help reset the connection and address any issues with the hardware.
5. Check for malware: Run a full system scan with a reputable antivirus program to make sure that your computer doesn’t have any malicious software that could be interfering with your network adapter.
6. Check your firewall settings: If you have a firewall installed, check its settings to make sure that it is allowing the necessary traffic to access your network.
7. Try another device: If you have another device on hand, such as another laptop or phone, try connecting to the network with that device and see if it works correctly. This will help you determine if the issue is with the network adapter or the network itself.
8. Try a different cable or port: If you have another available port on the router or another cable you can use, try connecting the network adapter to it and see if the connection works.
9. Power cycle the router: Unplug the router and leave it off for 5 minutes, then plug it back in and wait for it to finish booting. Some routers can become unresponsive if they haven’t been restarted in a while, and this can sometimes solve network issues.
10. Check for hardware issues: If none of the above steps work, there may be an issue with the physical hardware inside the network adapter. If possible, open the adapter and make sure that all the connections are intact and that there isn’t any visible damage or corrosion.
If none of these steps resolve the issue, you may need to replace the network adapter. If you do, make sure to purchase one from a reputable vendor that is compatible with your system.
